摘　　要：介绍了传统印制倒F型天线的工作原理和结构特性，详细分析了影响天线阻抗的因素。以一款支持蓝牙功能的GSM手机为例，通过ANSOFT公司的软件HFSS10.0进行仿真，设计了一款体积小、性能好的蓝牙天线。该天线工作于2.4-2.483GHz频段、尺寸只有16mm×4.5mm，10dB阻抗带宽为5％。改善后的PIFA天线成本低、结构紧凑、馈电方便，同时设计简洁、灵活，完全适于蓝牙系统应用。The basic operating principle and structural characteristics of traditional PIFA antenna are discussed in this paper. The factors influencing antenna impedance are analyzed in detail. An antenna prototype with a small area of 16×4.5 mm^2 on a GSM phone board has been constructed and analyzed with the software HFSS 10.0 of ANSOFT corporation. The operat- ing frequency is 2.4-2.483 GHz and -10 dB impedance bandwidth is approximately 5% centered at 2.45 GHz. This proposed antenna with low cost,compact structure,easy feeding and convenient design can be applied in Bluetooth system well.
